Voids and cavities in underground mines can pose a serious potential threat to worker and public safety due to the possibility of failure and collapse.
In order to develop proactive solutions to minimise subsidence risk where mine workings are present, the structural integrity, the geometry of the voids, their depth and condition, and the nature of the overlying strata must be determined.
Our unique investigations services can help Mine managers assess the stability of mine works and judge whether or not a cavity needs to be filled, whether work can proceed, and what project plans should be put in place to maximise productivity and safety.
We have the unique robotic borehole deployable cavity scanner(C-ALS) for a 360° view of underground voids, underground camera and borehole geophysical logging. This enables laser scanning of voids in order to create geo-referenced 3D models of subsurface conditions.
We are able to deliver the raw data or edited in closed 3D model and within seconds of finishing the survey. Point could data can be delivered and exported to clients’ modelling software on site.
